Abstract: Method and system for self-assessment of drinking behavior. According to one embodiment, the method includes examining a transdermal alcohol response curve obtained from a drinking event, querying a user on their feelings of intoxication after or during the event, and using the combination of the objective measurement and subjective feelings of intoxication to provide an alert or status during subsequent drinking events. In so doing, the method mitigates at least some of the drawbacks associated with conventional alcohol monitoring devices by correlating an individual's reported feelings of intoxication with an objective transdermal measurement of alcohol.

Abstract: A device having a hopper and a reservoir is provided enabling a tray of plants positioned in the hopper to move alone a Z-axis, and rotate about a Y-axis such that the tray of plants may enter the reservoir at a fixed positioned. The reservoir may be filled with a liquid solution indented to give a benefit to the plants. Handles connected to the hopper are biased in a top position via a pair of biasing member. The handles enable a user to operate the device by allowing the rotation and movement of the hopper during use.

Abstract: Waterless electrochemical transdermal alcohol sensor. In one embodiment, the sensor includes a proton exchange membrane imbibed with an imbibing liquid that includes at least one cationic substance that is liquid at room temperature. As examples, the cationic substance may be one or more ionic liquids with an imidazolium, phosphonium, ammonium, pyridinium, pyrrolidinium, or sulfonium backbone structure. The imbibing of the proton exchange membrane with the cationic substance obviates the need for the periodic addition of water to the electrochemical cell. The sensor additionally includes a sensing electrode, which is bonded to one side of the proton exchange membrane, and a counter electrode and a reference electrode, both of which are bonded to the opposite side of the proton exchange membrane. The sensor may be incorporated into a wearable transdermal alcohol sensor device, which, in turn, may be incorporated into a system for detecting transdermal alcohol.

Abstract: The disclosure describes the use of image sensors in a variety of different imaging applications. In some implementations, the pixels of an image sensor may be configured (e.g., programmed) with one or more analog filters to sense a variety of things, including, for example: average intensity and color (like a standard camera), 3D depth (like a time of flight or structured light camera), changes and/or motion in an image (like an event based camera), spectral reflectance (like a spectroscopy camera), and many other features of an imaged scene or object. In alternative implementations, digital filtering may be applied to the output of an image sensor to realize one of these applications.

Abstract: An interlock data collection and calibration system has a device computer, and a gas sample delivery system for delivering a first gas sample and a second gas sample to the ignition interlock device, the first and second gas samples having different predetermined concentrations of alcohol. The device computer includes a calibration program for calibrating the ignition interlock device using the first gas sample, and then delivering the second gas sample to the ignition interlock device to verify that the ignition interlock device correctly determines the second alcohol concentration of the second sample gas.

Abstract: A near-eye light field display for use with a head mounted display unit with enhanced resolution and color depth. A display for each eye is connected to one or more actuators to scan each display, increasing the resolution of each display by a factor proportional to the number of scan points utilized. In this way, the resolution of near-eye light field displays is enhanced without increasing the size of the displays.
